I am going to quote myself below because I posted this in the Watering Hole when it should more rightly be in the Nexus section in order to get some input. Quite possibly someone will tell me that I am missing the obvious and here is how to fix the issue, at least I hope so.
Well, I am enjoying my GNex for the most part, although I do have a couple of things that I do not like and that is with the contacts part of the system. I'll list those issues here in case someone knows a solution.
First, the phone adds my Google+ contacts to my Phone contacts list. This would not be a problem if the only people I view in Google+ were people that I call, but some of the people I follow in Google+ are just people that are worth following, but I don't want to have to go through them when looking for a phone number. I looked and I did not find a setting that would let me say only sync a Google+ contact into phone contacts if they are in my phone list. I do however want the Google + app to sync on its own so that the information I want to see is there when I want to see it and that I can get the appropriate notifications.
The second issue I have with contacts is there are some contacts that I do not want to actually show up and I was able to do this on the old version of Android. Here are two examples of how this is useful. I had a someone who kept calling my personal phone number for a work related issue (employees gave out my number when they shouldn't have) and no matter how many times I told them to use the business line they kept calling me, so I created a group in Google Voice called Block and whenever their numbers called me they got a message referring them to the business phone. I did not want to see these numbers in my contact list so I prevented them from appearing on the phone. The other thing I found useful is I signed up for text updates from some businesses and in order to be able to quickly identify who these texts were coming from I created a contact for them with their name and a picture placed that contact in a text message group and hid the group. By doing this when I got a text message from them instead of having the message say it came from some odd number it says it came from who they are with an identifying picture without cluttering up my phone directory with useless information.
I could do this before but can't seem to do so now.
